The "first-cross" method was something I became aware of through an audio presentation given by Linda-Bradford Raschke. This method uses the 3-10 momentum indicator (which you can read about thanks to AfraidtoTrade.com here and, to a lesser extent here).
The rules are simply (for a long position) buy the first pullback in the fast oscillator after the slow line crosses above zero for the first time. Obviously for a short the rules are simply the reverse; sell the first pullback in the oscillator after the slow line crosses below zero for the first time. Essentially, this method is indicating a higher high/lower high and, therefore, a place to enter a trend.
To demonstrate, here's a chart from today in HES. I didn't take the first long trade, but I did trade the short position later in the day.
It can certainly be applied to any timeframe, so long as you adjust your risk management appropriately.
The setups I include on this blog are used in conjunction with the 3/10macd and the criteria I ascribe to it as a way to alert me to an existing condition of price. The key concept to take away from this blog is that I try to anticipate what will happen on the higher time frame by using a faster time frame to trigger the trade setup. I do not trade a "system" I use two indicators to clue me in to price conditions. Please read the Disclaimer located in the sidebar of this site. I can be contacted via email at email@example.com
